Additional Notes

The Hyundai Kona Electric uses the 904 bulb for the map light across the 2019-2024 model years, with the 2019 fitment applying to vehicles produced from August 1, 2018 onward.
The 904 is an ANSI-standardized bulb type recognized in both the United States and Canada, operating at 12 volts and 8 watts.
The 904 follows the T10 wedge form factor, a miniature wedge base design that connects by pressing directly into a socket without a separate locking mechanism.
At 8 watts, the 904 draws a relatively low current load, which is consistent with interior courtesy lighting applications such as map lights.
The T10 designation refers to the bulb's tubular envelope width, expressed in eighths of an inch, placing it among the smaller wedge-base bulbs used in automotive interiors.
Because the 904 is an ANSI-designated type, substitutions should match the same voltage, wattage, and base configuration to maintain correct fitment and avoid socket or circuit incompatibility.
